The 50 Americans Who Gave Away the Most Money in 2012

This is the 13th year the Chronicle of Philanthropy has put together its Philanthropy 50, a list of the 50 biggest charitable donors in the past year. The list tallies gifts and pledges of cash and stock to nonprofit organizations. The Chronicle does not count gifts that donors made from their family foundations, to avoid counting the same gifts twice. In addition to cash and stock donations, the 2012 list includes art donations to two museums. The top 50 donors gave away a total of $7.4 billion last year.
